The RomanDigital app provides a clock of unique style that can be used to repurpose an old device or to display time on a current model.For more personal use, the RomanDigital widget makes a distinctive addition to a device's Home screen.
RomanDigital includes features expected in an ordinary digital clock, such as:
* Choice of 12 or 24 hour format
* Optional AM/PM indicator (uniquely integrated into the time display)
* Option to keep display on when app is in the foreground
* Display in either portrait or landscape
RomanDigital also includes:
* Independent configuration of app and widgets.
* Selectable app and widget time display typeface (monospace, sans-serif, or serif).
* Variable widget background opacity that can be set from 0% to 100% by tens.
* Selectable widget time zone.
* Selectable widget layouts to add a time zone label.
* Selectable app time display color.
For more detailed information including a FAQ list, please see the README.md file accompanying the RomanDigital source code.

WhatsNew:
Fixed:
* (v3.0.2) Crash on start or restart of widget update service occurring in an unforeseen circumstance; fix prevents crash and presents a dialog with options for how to proceed.
* (v3.0.1) Possible crash on start or restart of widget update service.
New in version 3.0.0
Added:
* Selection between monospace, sans-serif, and serif typeface to both app and widget settings.
Replaced:
* Exact-alarm-based widget updating with Service-based widget updating responsive to Android's time tick sig
Hint: This app is available in both, F-Droid Main and IzzyOnDroid repos.
While you can download the APKs here directly, you should preferably use an F-Droid client so the app stays up-to-date on your device.
